I thought about it but A freind has 3s and is almost equal to the nitros laks a little on top but has more tourq. I figure if I went 4s it would be a nitro killer and they would make us start a new class which would suck.
20 miniutes would be perfect I may go 8000 just to be safe.
small vid from the track it will be raced at
